DisplayLink Provides USB GPU Support On Linux

Phoronix: DisplayLink Provides USB GPU Support On Linux

Besides Intel, VIA, and ATI/AMD cooperating with X.Org and Linux developers by providing source code and documentation to help with the enablement of their hardware under Linux, another major company has come to the open-source table. No, sadly it is not NVIDIA...

The USB 2.0 specification says you can have up to about 16 feet of cabling between you and your computer. You put a hub in there and you can double that, possibly.

Hell if you got money to burn you cuold get a dozen of those USB adapters and do weird things... maybe make a light wall or something

I busted the LCD on a old laptop.. it would make a perfect little car media system if I could use of those USB video adapters. Little 800x600 vga screens can be had for reasonable prices nowadays. Just velco the VGA adapter to the back and make a custom cable and your set. It can literally be placed anywere inside of a car. Would be fun for road trips.

Nice! I am not sure if I will ever need it, but it's great that it's opensource. Thank you

michael:
on opentheblob.com is much spam in the last months. what about putting everything that has [url=http or [link=http: inside in a second list and remove from that list all spam? if there are any on spam messages (i doubt it) put them pack. A clean list would certainly more professional. Thanks.

What advantage does this have over the existing USB display adapters Linux supports?

This is not about video cards attached to the PC via USB (like SiS USB)[1]. DisplayLink technology allows to carry the video signal over a USB cable. The content of the screen is read from the framebuffer and sent over an USB cable to the monitors (which of course shall have a proper input).

[1] Yeah ok, you can also use that, but it's rather uninteresting (mainly for retro-compatibility).
